摘要： An implantable medical device system and method are provided for synchronizing atrial cardioversion shocks to the ventricular rhythm using an adjustable atrial cardioversion/defibrillation ventricular refractory period. Upon determining a need for an atrial shock therapy, the method determines if the ventricular rate meets synchronization criteria based on an upper ventricular refractory period limit. If synchronization criteria are not met, the refractory period is automatically adjusted in stepwise decrements until the synchronization criteria are met, or until a lower refractory period limit is exceeded. If synchronization criteria are met, an atrial shock is synchronized to the next ventricular depolarization occurring outside the current refractory period. If the lower refractory period limit is exceeded, the atrial therapy is aborted.

摘要： Control of defibrillation therapy delivered by implantable medical devices (IMDs) using hemodynamic sensor feedback is disclosed. The hemodynamic sensor feedback allows for increased control over application of atrial defibrillation therapy. Specifically, the therapy is delivered when a fibrillation episode results in a discrete loss of hemodynamic function. Defibrillation therapy is thus withheld for hemodynamically benign arrhythmias.

摘要： Techniques for detecting atrial fibrillation via a ventricular lead are described. An implantable medical device according to the invention may monitor a ventricular depolarization rate via the ventricular lead in order to detect the effect of conducted atrial fibrillation of the ventricular rate. For example, the implantable medical device may detect an increase in the ventricular rate, or a decrease in the stability of the ventricular rate. The implantable medical device may also detect the effect of delivery of a pacing pulse on the length of an R-R interval subsequent to the delivery. A compensatory pause following delivery of a pacing pulse may indicate the presence of conducted atrial fibrillation. The implantable medical device may store information relating to detected episodes of atrial fibrillation for later review by a physician, so that atrial fibrillation may be diagnosed in situations where it might not otherwise be detected.

摘要： AbstractThe invention relates to the use of atrial pacing therapies to treat atrial tachycardia (AT). When an AT episode is detected, an implantable medical device applies an ATP therapy. If the AT episode persists, the ATP therapy may be automatically reapplied at a later time during the course of the same AT episode. In particular, previously used ATP therapies are reapplied when episodic conditions, such as cycle length or cycle regularity, change. Although a particular ATP therapy initially may be unsuccessful in terminating the AT, it may prove successful when the cycle length or regularity of the atrial rhythm changes. As the rhythm slows down, the AT may be more responsive to ATP therapies that were previously unsuccessful. As a result, potentially efficacious ATP therapies can be reapplied to terminate AT episodes, and reduce the number of episodes that require more aggressive termination by painful, atrial shocks.
摘要翻译：摘要本发明涉及心房起搏疗法治疗房性心动过速AT的应用。当检测到AT发作时，可植入医疗装置应用ATP疗法。如果AT发作持续存在，ATP疗法可能会在同一AT发作过程中的以后时间自动重新应用。特别是，当诸如循环长度或循环规律性等情况时，先前使用的ATP疗法将被重新应用。尽管特定的ATP疗法最初可能不能终止AT，但是当心房节律的周期长度或规律性发生变化时，可能会成功。随着节奏减慢，AT可能对以前不成功的ATP疗法更有反应。因此，可以重新应用潜在有效的ATP疗法来终止AT发作，并通过痛苦的心房休克减少需要更积极终止的发作次数。

摘要： An implantable cardioverter including two electrodes for sensing depolarizations of a chamber of a patient's heart one, electrode providing a near field signal, one electrode providing a far field signal. The device defines a desired cardioversion pulse delivery time as a first time interval following the onset of the far field signal. The device measures a second time interval between the onset of the far field signal and the detection of the near field signal, and delivers the cardioversion pulse synchronized to the detection of the near field signal, using the first and second time intervals to define a synchronization interval following detection of the near field electrogram.
